Abstract

An automatic discharge device comprises a housing adapted to receive a container therein. An actuator arm is attached to the housing and movable between first and second positions. The actuator arm includes a dispensing bore therein. A drive unit is provided for automatically moving the actuator arm into one of the first and second positions in response to a signal from at least one of a timer, a sensor, and a manual switch. The actuator arm is adapted to engage and actuate a nozzle of the container in the first position and allow a fluid disposed in an interior of the container to be dispensed through the nozzle and the dispensing bore of the actuator arm.

Claims

1. A method of discharging a fluid from an automatic discharge device, comprising:

securing an aerosol container having a fluid and a nozzle disposed thereon within a seat of a housing of an automatic discharge device having an actuator arm that includes a main portion thereof extending substantially adjacent an axial length of the container and an overhang portion extending over and adjacent to the nozzle; and

pulling the main portion of the actuator arm with a drive unit in response to an input signal from at least one of a manual switch, a timer, and a sensor along a path substantially parallel to the axial length of the container to actuate the nozzle thereof by the overhang portion, thereby discharging the fluid from the nozzle and through a dispensing bore of the actuator arm.

2. The method according to claim 1, wherein the sensor is a light sensor.

3. The method according to claim 1, wherein the nozzle is depressed in a direction substantially parallel to the axial length of the container.

4. The method according to claim 3, wherein the fluid is dispensed in a direction substantially parallel to the axial length of the container .

5. An automatic discharge device, comprising:

a housing adapted to receive a container therein;

an actuator arm attached to the housing and movable between first and second positions, wherein the actuator arm includes a dispensing bore therein; and

a drive unit for automatically moving the actuator arm into one of the first and second positions in response to a signal from at least one of a timer, a sensor, and a manual switch, wherein the actuator arm is adapted to engage and actuate a nozzle of the container in the first position and allow a fluid disposed in an interior of the container to be dispensed through the nozzle and the dispensing bore of the actuator arm, and wherein an orifice of the nozzle directs the fluid substantially upwardly along an axial length thereof into the dispensing bore of the actuator arm.

6. The automatic discharge device of claim 5, wherein the fluid emitted through the dispensing bore is dispersed substantially uniformly into an environment around the housing.

7. The automatic discharge device of claim 5, wherein the fluid disposed in the interior of the container is an aerosol.

8. An automatic discharge device, comprising:

a housing adapted to receive a container therein;

an actuator arm attached to the housing and movable between first and second positions, wherein the actuator arm includes a dispensing bore therein; and

a drive unit for automatically moving the actuator arm into one of the first and second positions in response to a signal from at least one of a timer, a light sensor, a motion sensor, and a manual switch, wherein the actuator arm is adapted to engage and actuate a nozzle of the container in the first position and allow a fluid disposed in an interior of the container to be dispensed through the nozzle and the dispensing bore of the actuator arm.

9. The automatic discharge device of claim 8, wherein the fluid disposed in the interior of the container is an aerosol.

10. An automatic discharge device, comprising:

a housing adapted to receive a container therein;

an actuator arm attached to the housing and movable between first and second positions, wherein the actuator arm includes a dispensing bore therein; and

a drive unit for automatically moving the actuator arm into one of the first and second positions in response to a signal from at least one of a timer, a sensor, and a manual switch, wherein the actuator arm is adapted to engage and actuate a nozzle of the container in the first position and allow a fluid disposed in an interior of the container to be dispensed through the nozzle and the dispensing bore of the actuator arm, and wherein the nozzle of the container is rotatable about an axial length thereof to dispense the fluid.

11. The automatic discharge device of claim 10, wherein the fluid disposed in the interior of the container is an aerosol.

12. An automatic discharge device, comprising:

a housing adapted to receive a container therein, wherein the housing includes a pivotally mounted cover;

an actuator arm attached to the housing and movable between first and second positions, wherein the actuator arm includes a dispensing bore therein; and

a drive unit for automatically moving the actuator arm into one of the first and second positions in response to a signal from at least one of a timer, a sensor, and a manual switch, wherein the actuator arm is adapted to engage and actuate a nozzle of the container in the first position and allow a fluid disposed in an interior of the container to be dispensed through the nozzle and the dispensing bore of the actuator arm.

13. The automatic discharge device of claim 12, wherein a manual switch is disposed on the housing and actuable by squeezing the cover adjacent the switch.

14. The automatic discharge device of claim 12, wherein the fluid disposed in the interior of the container is an aerosol.
